The Prophet of Zod Fixes the Dumbest Christian Analogy

Wouldn't it be dumb if an unborn baby claimed his mother didn't exist just because he couldn't see her?  That's the scenario proposed by a stupid Christian analogy.  I recently saw it circulating Facebook and have run into it many times before in my history as a Christian.  But does this make sense?  Does this story show how stupid skepticism is and how smart faith is?  Or does it just take advantage of obvious storytelling tricks to belittle atheists in the eyes of Christians?  (Spoiler - it's the second).
